SummaryThe idea that underpins this project is to use the material evidence from thousands of surviving 15th-c. books, as well as unique documentary evidence — the unpublished ledger of a Venetian bookseller in the 1480s which records the sale of 25,000 printed books with their prices — to address four fundamental questions relating to the introduction of printing in the West which have so far eluded scholarship, partly because of lack of evidence, partly because of the lack of effective tools to deal with existing evidence. The book trade differs from other trades operating in the medieval and early modern periods in that the goods traded survive in considerable numbers. Not only do they survive, but many of them bear stratified evidence of their history in the form of marks of ownership, prices, manuscript annotations, binding and decoration styles. A British Academy pilot project conceived by the PI produced a now internationally-used database which gathers together this kind of evidence for thousands of surviving 15th-c. printed books. For the first time, this makes it possible to track the circulation of books, their trade routes and later collecting, across Europe and the USA, and throughout the centuries. The objectives of this project are to examine (1) the distribution and trade-routes, national and international, of 15th-c. printed books, along with the identity of the buyers and users (private, institutional, religious, lay, female, male, and by profession) and their reading practices; (2) the books' contemporary market value; (3) the transmission and dissemination of the texts they contain, their survival and their loss (rebalancing potentially skewed scholarship); and (4) the circulation and re-use of the illustrations they contain. Finally, the project will experiment with the application of scientific visualization techniques to represent, geographically and chronologically, the movement of 15th-c. printed books and of the texts they contain.

SummaryQuantum optics, the study of how discrete packets of light (photons) and matter interact, has led to the development of remarkable new technologies which exploit the bizarre properties of quantum mechanics. These quantum technologies are primed to revolutionize the fields of communication, information processing, and metrology in the coming years. Similar to contemporary technologies, the future quantum machinery will likely consist of a semiconductor platform to create and process the quantum information. However, to date the demanding requirements on a quantum photonic platform have yet to be satisfied with conventional bulk (three-dimensional) semiconductors.
To surmount these well-known obstacles, a new paradigm in quantum photonics is required. Initiated by the recent discovery of single photon emitters in atomically flat (two-dimensional) semiconducting materials, 2DQP aims to be at the nucleus of a new approach by realizing quantum optics with ultra-stable (coherent) quantum states integrated into devices with electronic and photonic functionality. We will characterize, identify, engineer, and coherently manipulate localized quantum states in this two-dimensional quantum photonic platform. A vital component of 2DQP’s vision is to go beyond the fundamental science and achieve the ideal solid-state single photon device yielding perfect extraction - 100% efficiency - of on-demand indistinguishable single photons. Finally, we will exploit this ideal device to implement the critical building block for a photonic quantum computer.

SummaryThe realization of “the internet of things” is inevitably constrained at the level of miniaturization that can be achieved in the electronic devices. A variety of technologies are now going through a process of miniaturization from micro-electromechanical systems (MEMS) to biomedical sensors, and actuators. The ultimate goal is to combine several components in an individual multifunctional platform, realizing on-chip technology. Devices have to be constrained to small footprints and exhibit high performance. Thus, the miniaturization process requires the introduction of new manufacturing processes to fabricate devices in the 3D space over small areas. 3D printing via robocasting is emerging as a new manufacturing technique, which allows shaping virtually any materials from polymers to ceramic and metals into complex architectures.
The goal of this research is to establish a 3D printing paradigm to produce miniaturized complex shape devices with diversified functions for on-chip technologies adaptable to “smart environment” such as flexible substrates, smart textiles and biomedical sensors. The elementary building blocks of the devices will be two-dimensional nanomaterials, which present unique optical, electrical, chemical and mechanical properties. The synergistic combination of the intrinsic characteristics of the 2D nanomaterials and the specific 3D architecture will enable advanced performance of the 3D printed objects. This research programme will demonstrate 3D miniaturized energy storage and energy conversion units fabricated with inks produced using a pilot plant. These units are essential components of any on-chip platform as they ensure energy autonomy via self-powering. Ultimately, this research will initiate new technologies based on miniaturized 3D devices.

SummaryRelative to other species, humans are characterised by considerable biological diversity despite genetic homogeneity. This diversity is reflected in skeletal variation, but we lack sufficient understanding of the underlying mechanisms to adequately interpret the archaeological record. The proposed research will address problems in our current understanding of the origins of human variation in the past by: 1) documenting and interpreting the pattern of global hunter-gatherer variation relative to genetic phylogenies and climatic variation; 2) testing the relationship between environmental and skeletal variation among genetically related hunter-gatherers from different environments; 3) examining the adaptability of living humans to different environments, through the study of energetic expenditure and life history trade-offs associated with locomotion; and 4) investigating the relationship between muscle and skeletal variation associated with locomotion in diverse environments. This will be achieved by linking: a) detailed study of the global pattern of hunter-gatherer variation in the Late Pleistocene and Holocene with; b) ground-breaking experimental research which tests the relationship between energetic stress, muscle function, and bone variation in living humans. The first component tests the correspondence between skeletal variation and both genetic and climatic history, to infer mechanisms driving variation. The second component integrates this skeletal variation with experimental studies of living humans to, for the first time, directly test adaptive implications of skeletal variation observed in the past. ADaPt will provide the first links between prehistoric hunter-gatherer variation and the evolutionary parameters of life history and energetics that may have shaped our success as a species. It will lead to breakthroughs necessary to interpret variation in the archaeological record, relative to human dispersals and adaptation in the past.

SummaryGas turbines are an essential ingredient in the long-term energy and aviation mix. They are flexible, offer fast start-up and the ability to burn renewable-generated fuels. However, they generate NOx emissions, which cause air pollution and damage human health, and reducing these is an air quality imperative. A major hurdle to this is that lean premixed combustion, essential for further NOx emission reductions, is highly susceptible to thermoacoustic instability. This is caused by a two-way coupling between unsteady combustion and acoustic waves, and the resulting large pressure oscillations can cause severe mechanical damage. Computational methods for predicting thermoacoustic instability, fast and accurate enough to be used as part of the industrial design process, are urgently needed.
The only computational methods with the prospect of being fast enough are those based on coupled treatment of the acoustic waves and unsteady combustion. These exploit the amenity of the acoustic waves to analytical modelling, allowing costly simulations to be directed only at the more complex flame. They show real promise: my group recently demonstrated the first accurate coupled predictions for lab-scale combustors. The method does not yet extend to industrial combustors, the more complex flow-fields in these rendering current acoustic models overly-simplistic. I propose to comprehensively overhaul acoustic models across the entirety of the combustor, accounting for real and important acoustic-flow interactions. These new models will offer the breakthrough prospect of extending efficient, accurate predictive capability to industrial combustors, which has a real chance of facilitating future, instability free, very low NOx gas turbines.

SummaryThe current trend in biophotonics is to try and replicate the same ease and precision that our hands, eyes and ears offer at the macroscopic level, e.g. to hold, observe, squeeze and pull, rotate, cut and probe biological specimens in microfluidic environments. The bidding to get closer and closer to the object of interest has prompted the development of extremely advanced manipulation techniques at scales comparable to that of the wavelength of light. However, the fact that the optical beam can only access the microfluidic chip from the narrow aperture of a microscopic objective limits the versatility of the photonic function that can be realized.
With this project, the applicant proposes to introduce a new biophotonic platform based on the all optical manipulation of flexible photonic metasurfaces. These artificial two-dimensional materials have virtually arbitrary photonic responses and have an intrinsic exceptional mechanical stability. This cross-disciplinary project, bridging photonics, material sciences and biology, will enable the adoption of the most modern and advanced photonic designs in microfluidic environments, with transformative benefits for microscopy and biophotonic applications at the interface of molecular and cell biology.

SummaryThis project is a comparative anthropology of conscience, ethics and human rights. Numerous international human rights documents formally declare their commitment to protect freedom of conscience. But, what is conscience and how do we know it when we see it? How do we distinguish it from self-interest or fanaticism? And what happens when the concept, often associated with a distinct Christian or liberal history, travels across cultural boundaries? The project will examine the cultural conditions under which claims to conscience are made possible, and the types of claims that are most persuasive when doing so. The project addresses these issues through the comparative analysis of three case studies: British pacifists, Sri Lankan activists, and Soviet dissidents. These case studies have been carefully chosen to provide globally significant, but contrasting examples of contests over the implications of claims to conscience. If claims of conscience are often associated with a specifically liberal and Christian tradition, mid-twentieth century Britain can be said to stand at the centre of that tradition. Sri Lanka represents a particularly fraught post-colonial South Asian counterpoint, wracked by nationalist violence, and influenced by ethical traditions associated with forms of Hinduism and Buddhism. Soviet Russia represents a further contrast, a totalitarian regime, where atheism was the dominant ethical language. Finally, the project will return specifically to international human rights institutions, examining the history of the category of conscience in the UN human rights system. This project will be ground breaking, employing novel methods and analytical insights, in order to producing the first comparative analysis of the cultural and political salience of claims of conscience. In doing so, the research aims to transform our understandings of the limits and potentials of attempts to protect freedom of conscience.

Summary"Chemical elements are the building blocks of life. The major elements, C, H. O, N, P, S are easily recognised as essential nutrients, but their use by life relies on metalloproteins. The identity of the metal centres of these metalloproteins and even the broader palette of trace elements fundamental to life are remarkably poorly known. Whole genomes remain opaque to decoding of this bioinorganic dimension, and optimal trace element concentrations for physiological function. Defining the elemental requirements for maximum growth rate of photosynthesising phytoplankton in the ocean, is critical to understanding Earth's climate. Although microscopic in stature, phytoplankton exert a gigantic influence on the biological pumping of carbon from the atmosphere to the deep ocean. Yet their metal requirements are poorly constrained, being inferred from cellular quotas and "nutrient-like" ocean metal distributions, susceptible to ambiguity between mistaken cellular uptake and use.
APPELS will undertake a two-pronged approach to define the modern marine metallome/metalloproteome. I will explore the expanse of the periodic table for novel required elements by growing phytoplankton, representative of the broadest chemotypes, in manipulated media, to delineate optimal conditions for growth whereby any limitation at lowered concentrations implies use. The second prong uses cutting-edge techniques that unite methods from proteomics with geochemical mass-spectrometry to allow both metals and their associated proteins to be examined comprehensively. APPELS will transform our understanding of the essential elements in the ocean and how the biological pump of carbon is geared to ocean chemistry in an evolving world. More broadly, APPELS will provide a step change in documented protein-metal binding centres, with implications for discovery of novel biochemical pathways, and optimal nutrition."

SummaryGlobular clusters (GCs) are enigmatic objects that hide a wealth of information. They are the living fossils of the history of their native galaxies and the record keepers of the violent events that made them change their domicile. This proposal aims to mine GCs as living fossils of galaxy evolution to address fundamental questions in astrophysics: (1) Do satellite galaxies merge as predicted by the hierarchical build-up of galaxies? (2) Which are the seeds of supermassive black holes in the centres of galaxies? (3) How did star formation originate in the earliest phases of galaxy formation? To answer these questions, novel population-dependent dynamical modelling techniques are required, whose development the PI has led over the past years. This uniquely positions him to take full advantage of the emerging wealth of chemical and kinematical data on GCs.
Following the tidal disruption of satellite galaxies, their dense GCs, and maybe even their nuclei, are left as the most visible remnants in the main galaxy. The hierarchical build-up of their new host galaxy can thus be unearthed by recovering the GCs’ orbits. However, currently it is unclear which of the GCs are accretion survivors. Actually, the existence of a central intermediate mass black hole (IMBH) or of multiple stellar populations in GCs might tell which ones are accreted. At the same time, detection of IMBHs is important as they are predicted seeds for supermassive black holes in galaxies; while the multiple stellar populations in GCs are vital witnesses to the extreme modes of star formation in the early Universe. However, for every putative dynamical IMBH detection so far there is a corresponding non-detection; also the origin of multiple stellar populations in GCs still lacks any uncontrived explanation. The synergy of novel techniques and exquisite data proposed here promises a breakthrough in this emerging field of dynamical archeology with GCs as living fossils of the past of galaxies.

SummaryWho are the people of Europe? This question is facing statisticians as they grapple with standardising national census methods so that their numbers can be assembled into a European population. Yet, by so doing—intentionally or otherwise—they also contribute to the making of a European people. This, at least, is the central thesis of ARITHMUS. While typically framed as a methodological or statistical problem, the project approaches this as a practical and political problem of assembling multiple national populations into a European population and people.
Why is this both an urgent political and practical problem? Politically, Europe is said to be unable to address itself to a constituted polity and people, which is crucial to European integration. Practically, its efforts to constitute a European population are also being challenged by digital technologies, which are being used to diversify census methods and bringing into question the comparability of national population data. Consequently, over the next several years Eurostat and national statistical institutes are negotiating regulations for the 2020 census round towards ensuring 'Europe-wide comparability.'
ARITHMUS will follow this process and investigate the practices of statisticians as they juggle scientific independence, national autonomy and EU comparability to innovate census methods. It will then connect this practical work to political questions of the making and governing of a European people and polity. It will do so by going beyond state-of-the art scholarship on methods, politics and science and technology studies. Five case studies involving discourse analysis and ethnographic methods will investigate the situated practices of EU and national statisticians as they remake census methods, arguably the most fundamental changes since modern censuses were launched over two centuries ago. At the same time it will attend to how these practices affect the constitution of who are the people of Europe.
